Abstract (en)

[origin: EP0342039A2] A Josephson device comprises a substrate (1), a first superconductive layer (2), a tunneling layer (3) and a second superconductive layer (4) which are laminated in that order. The tunneling layer (3) comprises a metal oxide having the same constituent element as those of a metal oxide superconductor which forms the first and second superconductive layers (2,4). The oxygen content of the metal oxide is less than that of the metal oxide superconductor.
